Whilst alive, Scorpius was an astronomer and had an apprentice named Phyrrys. He actually created the art, and has a constellation named after him.

Scorpius was later persecuted for his craft and his knowledge and instruments were almost totally lost. The art eventually returned to the world, as discovered in the Observatory Quest. This is covered in the Astronomy book in greater detail.

According to what Scorpius says, Zamorak has been observing the player.

Though he is a ghost, the player does not need an amulet of ghostspeak to talk to him. When you do talk to him, the chatbox says, "This powerful spirit seems capable of speaking to you even though you are not wearing an Amulet of Ghostspeak."

His grave seems to have a Zaros symbol on top of it, which would be strange as he is a Zamorakian. This is not the symbol of Zaros however, but a Celtic Cross.
